The proposed multi-spectral IFF beacon will use 40 to 50 % effient high power laser diodes at 863, 1064, and 1550 nm wavelengths. Thermal emitters including diamond-like carbon thin films, photonic crystals, and quantum cascade lasers will be characterized and compared. Finally a model to predict the detection range of IFF beacons will be developed using proprietary emitter power and atmospheric ...

Structural health monitoring (SHM) of large structures such as Navy ships requires an in depth knowledge of operational loads and how these loads may change over time. A network of low cost, wireless strain sensors can provide this information. During Phase I, we will demonstrate a highly synchronized, scalable network of energy harvesting wireless strain sensors. By converting ambient cyclic stra ...

Microbial contamination in kerosene based aviation fuels has been a problem for the USAF since the 1960’s. Antimicrobial effect of earlier used fuel system icing inhibitor (FSII) became an initial solution to this problem, but later, such fuel additives were banned due to their extreme toxicity towards humans. Newer FSIIs, being more eco-friendly, do not possess the antimicrobial properties of ...

Biodiesel is our next generation eco

This STTR seeks to develop a high-throughput, low-cost enabling technology for the manufacturing of electronic systems-on-film. It posits a novel concept of introducing percolation networks into semiconducting “inks” to increase by at least an order of magnitude the very low carrier mobilities (

A major limiting factor to organic cell efficiency is exciton diffusion and charge transport, which depend on charge carrier mobility in the E-fields created internally by the device materials and structure. Versatilis proposes a novel approach to ultimately improving >10% the efficiencies realized by typical organic solar cells, whether

A major limiting factor to organic photovoltaic (OPV) solar cell efficiency is exciton diffusion and charge transport, which depend in turn on carrier mobility and the E-fields created internally by the device materials and structure. Versatilis proposes a novel approach to enabling the better OPV cells from leading OPV makers to reach >10% efficiencies, whether

A critical military requirement exists for a fast, cost-effective, six-degrees-of-freedom (6DOF) technology that can track a pilot's helmet though rear-projection screens and is immune to distortion and interference from scatterers of magnetic/electrical energy. Building upon Phase I research that demonstrated feasibility of projecting light energy through graphics projection screens, Ascension T ...

The design of turbomachinery components is a complex process requiring many steps and hundreds of minute decisions in an iterative process. The design proceeds from meanline design through 3D viscous flow calculations (CFD) and finite element structural analysis (FEA). Design studies may traverse this design cycle many times, with routine tasks performed by engineers in a trial-and-error manner. ...

Space-based radar (SBR) requires multiple RF power amplifiers (PAs) to drive phased-arrays antennas. Control of the beam direction requires an amplitude range of 22 dB, and coupling between elements results in load impedances with significant mismatch. Both factors make conventional linear RF PAs very inefficient. The proposed approach employs a high-efficiency RF PA, class-S modulator, and e ...
